GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 709,356, dated September 16, 19102.

Application sied Jimmy 23,1902. serial No. 90.974. (No miei.)

To all whom it may concern,.-

Be itknown that l, JAMES W. PIPER, a citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Gas-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in combined burner-tubeand pilot-light which maybe detached whenever it may be desired to substitute a regular burner-tube therefor.

With this and other objects in view, which will readily appear-as the nature of the in'- vention is better understood, the same consistsin certain novel features of'construction and combination and Varrangement of parts, which will bephereinafter fully den scribed, defined in theappended claim, and illustrated in the accompanying drawings, in which-- Figure 1 is atop plan view of a gas-burner Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1. Fig. 3 is a transverse section on line 3 3 of Fig. 1. Figs. 4: and 5 are side views of the distributing-tube and one of the burner-tubes. Fig. 6 is a sectional view showing the substitution of a `regular burner-tube for the pilot-light.

The burner is. primarily designed foruse upon steam-propelled automobiles, but is susceptible of general use wherever a gas-burner is applicable.

Referring now more particularly to the drawings, the numeral l represents an air and gas supply pipe, and 2 a distributing pipe or tu be open'at one end forA the reception of the pipe 1 and closed at its opposite end.

Detachably mounted upon the tube 2 are a series of burner-tubes 3, which cross or eX- tend at right angles to said tube 2 and transversely. to the general direction of length of the burner. KThese tubes 3 and the tube 1 are 4formed .with matching recesses, (denoted et and 5, respectively,) which serve as ports or `passages through which the air and gas from the distributing-tube 1 pass into the several burner-tubes 3 for consumption. The recesses 5 in the tube l also form seats for the tubes 3, the side walls of said recesses holding the latter-named tubes in parallel relation. A bolt 6 passes downward through each pipe 3 and the pipe 1 and has applied thereto a nut 7, said bolt and nut detachably securing said pipe 3 and holding it seated in the recess 5. Each tube 3 is provided in its top with one or more longitudinal rows of jet-orifices 8 and has extending therethrough any desired number of vertical tubes 9, forming passages for the upiow of air from below. Surrounding the upper end of each of these passages is an annular row of minute jet-orifices 10. The

. air from the passages 9 coinmingles with the jets of gas issuing from the orifices 10, thus promoting combustion. It will be seen that by simply detaching the bolt 6 each tube may be quickly and conveniently7 removed for cleaning or repairs or the substitution of a new tube therefor. This detachable connection also permits of the use of dilerent forms and sizes of tubes in connection with the pipe 1. The drawings showthe tubes3 decreasing in length from the center to each end of the burner to give the burner an elliptical form in general outline; butthe burner may be made of any desired general form to correspond to any style of dre-box.

The transverse tube 3 at the inlet end of the burner dilers from the other tubes 3 in that it is not in communication with the tube 1, but is adapted to be supplied with gas through a supply-pipe 1l, said tube 3a thus being constructed to serve as a combined burner-tube and pilot-light. This construction is preferably employed when the burner is used on automobiles and in other relations where it is desirable at certain times to cut oit the greater portion of the heat and to Vmerely leave suihcient flame ro keep the water in the boiler heated and to light the other burners again when needed. Such .a contingency arisesin t-he use of a steam-propelled automobile when it is desired to reduce or `arrest the generation of steam while the vehicle is at rest and at the same time to keep the water in the boiler hot and secure the full heat from the burner within aminimum period when the time arrives to again put the vehicle in motion. By cutting off the supply of gas to the distributing-tube l the burner-tubes 3 will be thrown out of operation without aecting the tube 3, which will supply enough heat to keep the water in the boiler heated to the proper temperature and at the same time supply a flame to start the burner-tubes 3 when the dow of gas to the tube 1 is again started. If it be desired to extinguish the pilot-light Without extinguishing the ame from the burners, this may be accomplished by cutting o the gas from the pipe l1. As shown in Fig. 6, however, a regularform of burner-tube 3 may be substituted for the tube 3 when it is not desired toemploy a pilot-light attachment. The two tubes 3 3a are interchangeable and the detachable fastening permits of their ready application and removal at will.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the invention will be readily understood, and it will be seen that a burner possessing desirable and important advantages is provided.

While the preferred embodiment of the invention is as herein shown and described, Various changes iu the form, proportion, and

minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A gas-burner comprising a distributingtube and one or more transverseburner-tubes superposed upon the distributing-tube, said distributing and burner tubes being formed with matching segmental recesses, the recesses in the distributing-tube forming seats for the burner-tubes, each burner-tube having a longitudinal row of perforations, vertical air-passages and an annular row of jetorices around said passages, and fastenings detachably connecting the burner-tubes to the distributing-tube, substantially as described.

` In testimony whereofl have hereunto set my hand in presence of two subscribing wit- DQSSSS.
